front cover on photoshop

In our media lesson we were given cameras' and sent off to take some pictures for our school magazine the first 4 pictures above are the ones i took and i am going to use in my school magazine.
Next we had to upload the photos onto the computers and start making our front cover.
as you can see the last 2 pictures are screen grabs of my work. I cut around the person in my photo using the magnetic lasso on photoshop the last picture is what i have so far.
